Artificial intelligence to design and assess the wastewater treatment plant of the XXI century

LEQUIA researcher Manel Garrido Baserba defended his doctoral thesis on 4th March 2013. The thesis applied artificial intelligence techniques to face the increasing complexity of wastewater treatment plants.

Wastewater treatments are fundamental to keep our water natural resources. Wastewater treatment plants of the XXI century are high complexity systems that not only must fulfil technical requirements but also adapt to an increasing number of environmental and economic constraints. Within this framework, Environmental Decision Support Systems (EDDS) constitute a powerful tool to support the selection and integrated assessment of different wastewater treatment alternatives. An EDSS can be defined  as  interactive,  flexible  and  adaptable software,  which  links  numerical  models/algorithms  with  knowledge-based techniques, geographical information and environmental ontologies, and that can support environmental decision-makers.

In its doctoral thesis “Development of an environmental decision support system for the selection and integrated assessment of process flow diagrams in wastewater treatment”, Manel Garrido firstly carried out a wide research work on the complexity associated to the conceptual design of wastewater treatment plants (WWTs). This research allowed to define the necessary requirements for the software, as well as to select a methodology for the management and representation of data and acquired knowledge. Finally, the EDSS was validated considering different technical, economic and environmental scenarios and parameters. The results of these validations were published in international journals of the field. Manel Garrido’s work was supervised by Dr. Manel Poch (LEQUIA, Universitat de Girona) and Dr. Luis Larrea (CEIT, Universidad de Navarra), it is part of LEQUIA research line on EDSS, and has been carried out within the framework of the NOVEDAR_Consolider project  (
